|Item||IntraLase FS Femtosecond Laser|
|Description|| The IntraLase FS laser introduces new high precision femtosecond laser technology to ophthalmology. Surgeons now have the opportunity to offer their patients a safer, computer controlled alternative to a microkeratome for creating the corneal flap. By using the new IntraLase FS laser and proprietary IntraLASIK software, surgeons may avoid the complications related to the microkeratome and metal blade problems. The microkeratome uses a significant level of vacuum to applanate the cornea through a suction ring and hold it tightly as the metal blade slices across to create the flap.
The IntraLase FS laser creates the flap under very low vacuum, delivering the laser energy directly to the stromal layer of the cornea through a disposable glass lens. The outer surface of the cornea suffers no trauma, and the procedure is completely painless. In testing, grater flap stability as well as a high degree of accuracy in both the depth and size of the resections has been demonstrated.
What is the difference between a femtosecond laser and the excimer laser commonly used in vision correction procedures? The word femtosecond refers to the pulse duration of the laser as it impacts the cornea. The IntraLase FS laser uses a rapidly fired, very short pulse with a spot size of only 3 microns. This enables the IntraLase FS laser to apply less energy to the corneal tissue with micron range accuracy. Excimer lasers use a 193 nm wavelength which is absorbed at the cornea's outer surface, immediately ablation tissue upon contact.
The IntraLase FS laser uses a long wavelength (1053 nm) that is not absorbed but instead can pass through the cornea with absolutely no effect on tissue until it reaches the pre-programmed target. The Intralase FS beam is optically honed into a 3 micron spot size and precisely delivered via IntraLASIK computer software to the prescribed intracorneal location. The laser pulsed are placed close together to define precise subsurface areas of photodistruption.
